SAD-IRON.

Specication of Letters Patent.

Continuation in part of application Serial No. 703,046, ,1ed June 11, 1912. This application tiled January 22, 1914. Serial No. 813,721.

To all whom it may concem:

-Be it known that I, WILLIAM E. HoYT residing at New York, New York county, and State of New York, have invented and discovered certain new and. useful Improvements in Sad-Irons, of which the following is a specification.

ln the use of sad irons conditions are sometimes favorable to the use of gas as a heating agent, while under other conditions charcoal, or similar fuel, is more convenient for such purposes.

The object of my said invention is, therefore, to provide a sad iron which is capable of use either with gas or charcoal as a fuel, and it consists,I further, in certain details of construction relating particularly to the gas burner whereby these objects are advantageously attained, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings which are made a part hereof, and on whichsimilar reference characters indicate similar parts, Figure 1 is a side elevation of a sad iron of my improved construction with the gas burner attachment thereon, Fig. 2 a central longitudinal section through the same, Fig. 3 a rear elevation thereof, and showing the outline of the removable door in dotted lines,y Fig. 4 a horizontal section looking Fig. 2, with fender plate 40 omitted, Fig. 5 a horizontal section througlh the gas burner attachment, Fig. 6 a detai view of a form of rear door for the combustion chamber to be used when charcoal is employed as the fuel, Fig. 7 a detail view of the front end ofthe gas bur-ner, Figs. 8 and 9 are cross sections on the dotted lines 8-8 and 9-9, respectively, in Fig. 5.

ln said drawings the portions marked A represent the body of the sad iron, B the handle, C a heat deflecting plate, D my 1mproved gas burner attachment, and E the substitute rear door for use when charcoal is employed.

The body A is a castin of suitable form and arrangement, being ollow to form a combustion chamber and provided with a grate a, and a flue al with a damper 10 therein'. Suitable air openings 11 controlled by a sliding valve 12, are provided on each side ofthe combustion chamber, as indicated.

A strip of sheet metal 25 bent in the form of downwardly from the 'dotted line 4-4 in' slightly,

the'interior of the chamber within the iron extends around the interior of said chamber andi's spaced from the sides thereof to form airpassages from the openings 11- on either side to a pointv adjacent to the sides of the grate on the bottom of said chamber.

The handle B and deflecting plate C are of any appropriate or approved form and need no special description herein.

A fender plate 40 extends horizontally through the combustion `chamber above the burner and near the upper portion of the chamber, being supported on appropriate legs 41 and 42 and serving to establish an air chamber above the plate and protect the upper portion of the iron from the heat while at the same time deflecting the heat downwardly.

The gas burner attachment .D comprises a plate adapted to be inserted in vertical grooves on each side yof the rear opening leading into the combustion chamber in the body A and serves as a. door for` said opening. As will be noted by an inspection of Fig. 3, the sides of the rear opening leading into the combustion chamber are tapered' somewhat from the top inwardly toward the bottom, somewhat wider at the tov than at the bottom. The edges of door B, as indicated b dotted lines, are correspondingly tapered?, and at their upper ends have laterally projecting wings 26, so that when in its lowermost position the edges of said door will be retained by the iange around the sides and bottom of said opening, but when raised sufficiently to disengage the laterally projecting wings 26 at the upper end of the side edges of said door, the door will be released from said flanges and permit-ted to pass freely through the opening. Said door is formed with an opening d through its upper portion above the burner to admit air, but is otherwise adapted to close said opening when in position. The gas burner proper, D1, is formed integral with the door, or cast in piece therewith, and extends on each side thereof, its outer end being internally screw-threaded for attachment to a pipe section 13, and its .inner end being fan-shaped and divided into two dischar e openings 14, extending at an angle from te central opening piece 15 between them, as best shown in F1g. 5. Said gas burner extends at an angle from but said opening is formed and divided by an angle the door downwardly toward the bottom of the iron, as best shown in Fig. 2. r1`he pipe section 13 is provided with air inlet openings 16 near its outer end and a regulating sleeve 17, with corresponding openings 18, is mounted and adapted to turn thereon. By this meansany area of opening necessafry may be provided. and the supply of air through said openings regulated to' secure the proper mixture for obtaining the character of flame desired. rllhe outer end of pipe 18 is provided with a nipple section ,19 for attachment to the gas supply hose 2U,

The door E shown in ig. 6 is of appropriate construction for use with solid fuel and is provided with air inlets 21 controlled by a sliding valve 22 operated by a handle 23 in a common manner.

The grate a is of special construction and adapted to perform a two-fold purpose. The form and construction will be best understood by an inspection of .Figs 2 and 4. 1t extends a greater part of the length of the combustion chamber and is wide at its rear end and narrow at its forward end, with longitudinal air through its central portion and also through its shorter side ortions., lThis character of grate has been ound very eliicient when the iron is used for solid fuel, such as charcoal, with the character of door shown in Fig. 6 and the air and draft regulating devices. It is also especially adapted for use with the particular character of gas burner D1, the angularly positioned openings let directing the flame outwardly toward each side of the iron and the grate serving to spread the flame and deflect it over the entire bottom surface of the iron, thereby coperating Ver eliiciently with the articular character of urner, and to the e 'ciency of the iron when used with gas for the heatingl agent.

In operation, when it is desired t0 use said iron with as as a fuel, the gas supply pipe 20 is attaced to the gas supply.. The valve controlling said supply (not shown) is opened and the gas mixed with an appropriate supply of air coming through the openings 16, controlled by the sleeve 17, comes through the angularly' positioned vopenings 14 and is ignited at the outer end of burner D1. The burner is lighted and the mixture regulated /to secure the desired fiame before the burner is inserted in the iron. The o erator is thus conveniently enabled to adiust his flame and see that it is burning properly before the burner is placed in the combustio-n chamber. When this is done the door D is slid into place behind the overhanging flanges surrounding the entrance to the combustion chamber and may be locked in place by a button 30 mounted and adapted to turn on a screw 31 on the outer face of the rear handle post, or support. The downward inclination of the 'burner D1 directs the flame against spaces extending incassa the top surface of the bottom of the iron, while its flared outer end with the division 15 -between the two sides thereof, coperating with the particular form of grate a, which as now used serves as a flame spreader, insures that the flame will be spread Substanz tially across the entire surface of said bottom, thus securing a uniform degree of heat throughout said surface, and a maximum amount of heat with a minimum` quantity of gas. By this means very etlicient work may be accomplished by the use of the iron without heating the iron excessively, enabling the upper part of the iron to be maintained at a comparatively low temperature and thus avoid, to a considerable extent, much of the. discomfort commonly experienced in the use of the internally heated sad irons.

l/Vhen it is desired to use charcoal, or similar fuel, door D is removed and the door E is then substituted therefor. The charcoal is introducedand lighted in the well known manner, and the draft regulating devices adjusted so that the combustion chamber will be adapted for burning such fuel, and the work will proceed in the well known manner.

Having thus fully described my said invention, what 1 claim as new and desire to secure by Letters Patent is: 1. A sad-iron comprising a body formed with an internal combustion chamber having an open side with vertical retaining grooves at each side of said opening, a sliding plate with edges adapted to be mounted in and slide in said grooves to engage therewith and disengage therefrom,4 and formed with a gas burner as an integral part thereof, said gas burner extending part on one side of said plate and part on the other and in a direction inclined'inwardly toward the bottom of said combustion chamber, the inner end of said bur-ner being formed dared and with a multiple of discharge openings leading at angles each way from the central opening and the outer end of said burner being formed for the attachment of a gas pipe, substantially as set forth.
